最近获得的Au(n，2n)反应同质异能截面的准确数据为在Au靶核的所有可用反应数据的局部一致模型分析中考虑核的有效转动惯量问题提供了宝贵的机会。从而得到了Au核转动惯量等于刚体转动惯量的明确证明，并提出了Ir核转动惯量等于刚体转动惯量的推论。在入射能量高达≥40 MeV的情况下，进一步的测量也是有用的。
Recent accurate data obtained for the isomeric cross section of the Au(n, 2n) reaction provide a valuable opportunity to consider the question of the effective moment of inertia of the nucleus within a local consistent model analysis of all available reaction data for the Au target nucleus. Thus, a definite proof of a moment of inertia equal to that of the rigid–body has been obtained for Au nucleus while an inference of the half rigid–body value is suggested for the Ir nucleus. The usefulness of further measurements at incident energies up to ≥40 MeV has also been proved.
